Explanation

To evaluate this expression, follow the order of operations (PEMDAS):

1. Evaluate the expression inside the parentheses:

2 + 3 = 5

So, the expression becomes:

8 * 5 - 4^2

2. Multiply 8 and 5:

8 * 5 = 40

3. Calculate 4 squared:

4^2 = 16

4. Finally, subtract 16 from 40:

40 - 16 = 24
